VEHICLE-TIRE.

SPECIFICATION forming part of Letters Patent No. 755,147, dated March22, 1904.

Application filed June 8, 1903. Serial No. 160,507- (No model.)

Improvements in Vehicle Tires and Fellies, ofY

which the following is a specification.

This invention relates -to improvements in that type of pneumatic tireand felly in which the outer casing of the tire is detachable from thefelly to permit access to and removal of the inner tube; and the objectis to provide -a tire of this class and felly therefor with improvedattaching means whereby the tire may be readily and securely held to thefelly of the wheel and positively prevented` from creeping and toprovide means whereby the inner tube will be prevented from forcingbeneath the inner edge of the outer casing when in-1 flated.

`With the above object in view the invention consists in the novelfeatures of construction hereinafter fully described, particularlypointed out in the claims, and clearly illustrated by the accompanyingdrawings, in which- Figure 1 is a side elevation of a portion of a fellywith the tire attached thereto embodying my invention, and Fig. 2 atransverse sectional view of the same. Y

Referring now more particularly to saiddrawings, 1 designates the fellyof thewheel,

'provided about its periphery with the usual flat metal tire 2.Extending about the periphery of said metal tire 2 and centrallydisposed thereon is a'loclring member in the form of a metal plate orrim 3, having outwardlyflaring side walls 4, said member being firmlysecured in position by bolts 5 or other fastening devices which passthrough the base thereof and the tire 2 into the felly.

6 designates the outer casing or shoe, which' is split or open at itsinner periphery and enlarged to form the attaching portions 7, de-

signed to extend on each side-of the central rim 3, the inner faces ofsaid attaching portions 7 being beveled to correspond with the contourof the walls of said rim. Said attaching portions 7 are of such widththat when in position they extend slightly beyond the sides of thefelly, so as to be capable of compression by fianges or plates 8, whichare secured to the respective sides of the felly by suitable bolts 9.When said plates 8 are attached to the felly, the attaching portions 7of the outer casing are compressed and forced into close contact withthe Haring oroverhanging walls 4 of the rim or locking member 3, andthus said outer casing is rigidly heldv from disengagement from thefelly and positively prevented from creeping thereon. Within the outercasing is an inner inflatable tube 10, which when inated rests againstthe locking member Scand extends within the recess or groove formed bythe walls thereof. Any tendency of the inner tube when inflated to blowunder the edge of the outer casing is prevented by the rim 3. Itis notnecessary in attaching or removing the outer casingfto stretch the samein 'any manner, so that there is no tendency to Venlarge its diameter,as in the ordinary type of clencher-tire.

Having. thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is

l. The combination with a felly having a rigid band or rim extendingaround the periphery thereof, centrally disposed andof less widththanthe width of thefelly and provided with outwardly-flaring side walls, ofa tire comprising an outer casing split at its inner periphery andformed with attaching portions to fit on each side of the rim andproject beyond the sides of the felly, an inner iniatable casing adaptedto seat in the space between said flaring wall when iniiated., and

spective sides of the felly for compressing said attaching portions ofthe outer casing and forcing them into contact with the aring walls ofthe rim.

2. The combination with a felly having a rim extending around theperiphery thereof, centrally disposed and of less width than the widthof the felly and havingoutwardly-aring side walls and its outer faceprovided with a continuous recess, of a tire split at its innerperiphery and formed with attaching portions adapted to fit on each sideof the rim and projectbeyond the sides of the felly,clampingclamping-plates detachably secured to the re- IOO platesdetaehably secured to the respective to this specification in presenceof two Witsides of the elly adapted to compress said atnesses.Y tachingportions and force the same into contact with the Haring Walls of therim, and an PAUL W' LITCHFIELD 5 inatable inner casing adapted to extendinto Witnesses:

said recess of the rim. H. C. PARSONS,

In testimony whereof I have signed my name KATIE ORR.
